Two-CYCLE ROTARY-CYLINDER ENGINE.

Specification of Letters Patent.

Pau-atea July 2o, `1915.

Application filed May 13, 1915. Serial No. 27,820.

To all lwhom 'it may concern Be it known that I, JUAN BEiiNiino' Oiz- THoLAN, a citizen of Argentina, residing at No. 671 Calle Maip, Buenos Aires, Argeni tina, have invented an Improvement in Two- Cycle Rotary-Cylinder Engines, of which the following is. a specification.

The present invention relates to certain novel and useful improvements in the construction of rotary cylinder engines, and has for its object to provide means by which each one of the elements or cylinders-constitiiting it, may work in two cycles, instead of in four, as it is the common principle under which the engines of the abovesaid type work.

My present invention has in View to -increase the eiciency of the said type of engines up to a degree that has not been reached heretofore and taking into considera-tion the weight and the energy developed,

the eiiciency is about twice that lof the tour cycle system.

, The essential feature of my present invention consists in utilizing the centrifugal force as main agent for the discharge ofl the combustion gases yand for the admission ot the explosive gas or mixture in' a regular and perfect form during the cycle of each one of the cylinders, by which means a maximum of regularity andv eliciency in the working is obtained.

Although improved in certain details, the

i general construction of the engine does not differ from that of the ordinary engines and it is obvious that it may be altered, and that the number of cylinders may be increased or diminished, without in the least affecting the validity of my present invention.

The discharge step, the initial fraction of the same excepted, is eifected simultaneously with the admission, in such a form, that. though inverted, it is similar to the principle under which the usual two cycle engines mine the admission in the vcylinders' of the carbureting gases. -i

A practical embodiment of the invention is re resented in the accom ianyinof drawiiw.

forming a part ot' this specilication.and in which the igure is a sectional elevation of the improvement. A

' In the drawing 1 is a crank case. mounted on steel balls 2, which rotates on a standard and tubular axle 3, forming part of the crank-axle 4. The cylinders '5,l provided with lordinary radiators, have two series of holes 6 and 14. rl `he plungers l() move in the cylinders, actuating the connecting rods l1, which have their ends fixed on the head 1Q, secured to the crank-axle 4.

Tubes S lead from the crank case to the admission holes G which comprise a semicircle of the cylinder. To complete this semicircle, the holes les have been made which communicate unitedly with the l exhaust tube 13. rlhe tubes 13 extend outward approxiinately parallel with the cylini'lers and beyond the ends ofthe same. The tubes 13 not only serve as exhaust but in addition thereto serve to draw in, the explosive mixture from the crank case to the cylinders. The holes 1l` which start from the same level as the holes G', go somewhat higher up than the others, so that the displacement ot' the plunger uncovers a fraction of the lirstnamed, permitting thc exhaust only before uncovering also the second ones so as to realize the exhaust and theA ad-.

mission simultaneously.

At the surface of the plungers a seinicircular baille 15 has been placed before the holes (1 which produces the precipitation of the combustible gas against the head ot' the cylinder at thc saine time as the used gases are lislodgedfrom the same. The plungers are of sufficient length to cover in their furthest advance the whole of the holes' 16 and G. The gas is introduced into the crank case b v aspiration or b v means of a mechanical carburcter, through the tube 3 serving as an axle for the engine. In this way the accumulation of gas in the crank case is-maintained to supply the cylinders. It will be readily understood that the arc of circle run by the cylinders in their, rotary movement:

from the points where the pistons uncover the openings to where they close the said openings is so ample, it will be possible to fully discharge the burned gases and to'have them substituted by the carbureting gases,

on 'ground of the greater specific weight of thse latteand also of the circulation originated by the centrifugal force.-

Having now fully' tained the nature of rny said invention and in what manner the same is to be performed, I declare that whatl claim,"i`s:

A rotary internal combustion vengine of tlie-noii=co1np1ession type, comprising a revoiubie crank case, a plurality of cylinders mounted on the acrank case and havingV their inner ends opening into the same, pistons-in f the cyllnders, a crank :shaft 1n the crank ease, piston rods connecting the pistons with i, Geiles of txe vpatent may be obtained for described and ascer-y cylinder.

Washington, D. GI,

the crank shaft, an admission tube connecting the crank case with the inner end of each '-cy1inder, and an exhaust tube 'leading from each cylinder on the 'side opposite .the admission tube, and extendlng approximately for drawing in the explosive mixture to the JUAN BERNARDO ORTHOLAN.
